Seen them, played them, RUN AWAY!
Mike at Uke Republic got a couple & we all played w/them a couple of weeks ago, and another SE Uker got one of their "banjolele" models to play around with... following is MY OWN OPINION.
Pros: CHEAP! In the US, less than $50. Made from be solid wood. LIGHT (travel uke?) Has "zero-fret" like Fluke/Fleas
Cons: Tuners are similar to those found on an "autoharp" AKA "Zither" - thus the name & are adjusted using a "tuning wrench" - making new string break-in an interesting if not totally frustrating challenge! Frets are some sort of hard & clear plastic material that seem to be embedded into the solid one-piece neck (which is
really one-piece w/no harder-wood & separate fretboard). Sides are solid & apparently cut out of a single solid piece of wood & THICK. Tops & bottoms are thicker than usually encountered on ukes - probably due to no apparent bracing and the thick sides. Overall, these ukes are thinner than the thinnest currently available "travel uke". NOW, the "banjolele" - the top/skin is made of "Baltic birch"!! And... as you might expect, it is nearly the quietest of the lot!
Admitedly, your mileage may vary! You may LOVE these. We ukers are all just a bit "twisted" - "but in a good way"!
